Not much help to you, but I am wondering the same thing. My ZHP has been fantastic handling-wise, but the original kit is apparently MIA. Any advice on what would be a near-identical replacement handling and ride-quality wise is appreciated. I've been leaning towards the Cup Kit myself.

Already priced this out via bmwpartstore.com In comparing against the H&R/Bilstein Sport kit from Turner, I come in less than what bmwpartstore quoted me (about $200-300) and that is including a few things they did not include (front/rear reinforcement plates, diff bushings and new rtabs & limiters). I love dealing with them, however BMW's cost is higher than what I can find aftermarket. I guess I could save money and not get springs, but would hate do have them break and have to replace later.

Not sure what to do. I am hoping when I am ready to order I can see if Turner will cut a deal considering I am spending a chunk of money. Who knows...

The same thing as any other E46 ZHP or not! Unless you want to go stock again then just purchase the same parts as your car came with. it is debated that the sports package 330 and ZHP both use same springs and dampers. I am not 100% sure. if you are going aftermarket, none of that matters.

Where the hell can I buy this kit? Seems like as long as I am doing the LCAB's, I might as well do the control arms, shocks/struts/sway bar as well, no?

Would coilovers have any affect on the subframe? I've never heard of a subframe failure on a 330i Zhp package...

Coilovers have the potential to be harsher on the car because you have the ability have the car at a lower stance. The lower the stance, the more stress is being put on the all aspects of the car (frame/subframe, wheel bearings, differential, etc.). I do not need my car that low (my old 325i had a PSS9 kit), so I cannot justify the extra expense (>$400) for coilovers.

I also have not heard of any subframe issues with the facelifted (02-06) BMWs. However, I do not want to be the first to find out.

Whammy, I would highly recommend Eibach Sportline spings with Koni Yellow adjustables (I think they are on sale right now too). I have had that setup on my '05 ZHP for about 30k miles and love it. Rides just a tiny bit stiffer than a stock ZHP, while lowering it the perfect amount. We've spoken before when you were buying your ZHP, I'm local to you and if you haven't done your suspension yet you are welcome to go for a ride/drive in my ZHP to see what you think of the setup. I should have my car out of winter storage anytime now.

In my 325i, I rolled in a PSS9 kit. For this car, I do not want a coilover kit. I want to preserve the car as long as I can. Putting additional stress on the subframe is not an option for me.

With that said, what are my options? I have been doing some research on this and I had a few options:

H&R Cupkit

Bilstein Shocks w/H&R Springs (Not sure if Race or Sport)

Something else?

I would prefer to stay with either Bilstein or H&R due to reputation. Any thoughts on this?

I have the same setup and I agree, I love it! However, the Sportlines are pretty low, and the rake is pretty significant. I removed my rear spring pads to even out the height and the stance is perfect now.

I would recommend going with the Eibach Pro Kit instead of the Sportlines if you're not going for an aggressive drop! You can't go wrong with the Koni Yellows either. Awesome shocks.

Yeah, that would be great!

Thank you both for your input. This is what I was thinking of at the moment. It still could change as I have not bought anything yet.

I wanted to give everyone a little update post purchase. The old suspension and tie-rods came out pretty easily. New parts were subsequently reinstalled. Unfortunately, we did not get to any of the bushing work and saved that for another day.

When going for an alignment, the alignment shop could not get my car aligned. Front Adjustable camber plates and rear adjustable camber arms are needed to get the car into alignment. I am really shocked this is happening. It has certainly increased my budget for this project.

That does not sound right. I think you better get a second opinion on that.

This should not be too much of an issue for a shop that knows what they are doing. Front is adjustable and you should be able to get it within spec or very close and rear is adjustable enough to get back into spec.
